I having trouble starting my truck. But when it starts it stalls out quick if I don't put the gas pedal to the floor. It ran fine before I replaced the fuel filter and the spark plugs. I ran scan tools to see if there was any problem, but it didnt say anything. I heard that the scan tools don't work on spark plugs for older 1993s. There is to much fuel being released in to the throttle body. What can be the problem

I recommend you check the fuel pressure this will tell you something about the fuel pump/regulator/return line
